Specication of Letters Patent.

Patented April 9, 1907,

Application filed June 26,1906. Serial No. 323,465.

To @Zt whom it may concern;

Be it known that I, JOHN D. OBRms, a

citizen of the'- United States of America, and

a resident of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Sheet-Lathing Machines, of Which the following isa specification.

This invention relates to mechanisms for weaving sheet -lathing for buildings, and more' especially the type of such lathing which'forms the subject-matter of a companion application for Letters Patent, Serial No. 323,464; and the present improvement has for its object to provide a simple and durable construction and combination of parts whereb longitudinal slits are formed in a sheet of wood veneer to provide a series of longitudinal and integral strips, which are in turn deflected laterally to form sheds, into which the transverse separator-bars are in vturn introduced, the various operations being effected in a successive and automatic manner, all as will hereinafter more fully appear.

In the accompanying drawings, Figure 1 is a longitudinal section on line a: Fig. 2, of the machine in its preferred form. Fig. 2 is a transverse elevation with parts in section on line Fig. 1. elevation of the operating mechanism of the Fig. 4 is a detail horizontal section on line t2 Fig. 2. Fig. 5 is an enlarged detail longitudinal sectionon line ac3 :63, Fig; 6, of the slit-forming saw mechanism of the machine. Fig. 6 is an enlarged detail transverse section of thc Fig. Tis an enlarged detail longitudinal section on line fc Fig. 8, of the shed-forming mechanism. Fig. S is an enlarged detail transverse section of the same on line Fig.` 7. Fig. S) is a detail section on line 9:7 x7, l4 ig. 8, of the hopper and feedingplunger for the separator or weft bars contained in said hopper. F ig. l() is an enlarged detail plan of ond portions of two adjacent slats of the carrier-apron. Fig. 11 is a detail plan view of a port-ion of the lathing-sheet, illustrating the arrangement of the slitsin the same.

Similar numerals of reference indicate like parts in the several views.v j

Referring to the drawings, 1 represents the main frame of the machineof any usual and suitable construction and upon which the Fig. 3 is a detail side various mechanisms of the machine are supported or journaled, as hereinafter set forth.

, 2- and 3 are sprocket-carrying drums or wheels journaled to the frame 1 in separated relation and forming a support for the longitudinally-extending and endless carrier or apron hereinafter described.

4 is the endless carrier above referred to, comprising a series of transversely-arranged slats 5, attached to endless chains 6, which in turn have operative engagement with the sprocket-drums 2 and 3, as shown. In the present improvement the slats 5 are provided with a plurality `ofshed-forming projections 7 upon their upper faces, which projections are separated by interveningrecesses adapted to receive and permit thefree downward movement of the shed-forming plungers, as well as the series of slitting-saws hereinafter described. The projections of one slat has an alternated or interspaccd relation to the rows of suchprojcctions of the next adjacent slats, as illustrated more particularly in Fig. 10.

8 are central recesses formed in the projections 7 aforesaid to provide passage-ways for the weft-bars of the sheet-lathing, as hercinaftcr more fully set forth.

9 is a transverse guide-frame secured at its ends to the mainframe 1, as shown more particularly in Figs. 2, 7, and S.

1() are the transverse plurality of shedforming plungers heretofore referred to and which have vertical movement in the guideframe 9. Such plungers are formed at their lower ends with shed-forming projections 11 and central recesses 12, corresponding to the like parts of -thc slats 5 above described and adapted in conjunction therewith to constitutethe shed-forming means of the present machine, and said projections will preferably have the convex form shown, with -a view to effectingsheds in the lathing-sheets withouiI danger of fracture of the parts of said sheets.

The plurality of plungers l0 above described are e( ual in number to the combined number of the intervening recesses of' two adjacent slats 5 aforesaid, and each plunger is individual to an individual intervening recess of one or the other of said slats.A Such plungers are adapted to be alternately operated by means hereinafter described in two alternating series and witheaeh alternating. series individual'to the intervening recesses IOO ' strips bars or strips are automatically introducedA 'depending series of sheds adaptedl for the passage and reception of the weft bars or vof the sheet-lathing. and while weft- Ainto place by mechanism hereinafter described. 1 i

With such arrangement the saws receive rotary motion on the axis of their carrying-shafts and an orbital' motion around the axis of the shaft 21 and sothat in their orbital travel each bank of saws will out a` transverse series of longitudinal slits in the lathing-sheet and form therein the rowsof strips 13, before referred to.

25 is an idler-pulley mounted on the shaft 21 and ada ted to receive rotation by belt connection rom the power source and transmit said motion to the pulleys 36 on the saw- ',carryingshafts by belt connection 27, as

shown 1n Fig. 1.

28 is a belt-and-pulley connection between the cani-shaftl? and the shaft 2l for imposing movement in unison upon said shafts.

29 is a ratchet-Wheel secured to the shaft of the forward sprocket drum or wheel 2 of 'the endless carrier 4 aforesaid and provided with ratchet-teeth equal in number to the sprockets of said drum or wheel 2 and so at at each intermittent actuation of said ratchet-wheel the endless'carrier 4 will be advanced a distance e ual to the distance between the centers of t e slats 5 of the said carrier. Y 30 and 31 are a pair` of eccentrics set in opposed relation on the shaft 17 and provided with pawl-yokes A32a-nd 3 3, adapted to engage the ratchet-wheel 29 in common to impart twointermittent'impulses to the same in one revolution of said cam-shaft 17.
